Our read on this product
This pop-up emitter is designed to automatically manage stormwater runoff, directing it away from your home's foundation. It works by opening when water pressure builds up in your drainage system and closing when the flow stops, ensuring that excess water is released to a safe discharge point without any manual intervention.
Its low-profile design helps prevent tripping hazards and keeps the emitter flush with the ground when closed, which also protects it from lawn mower blades. The outside flange is intended to prevent grass from growing over the cover, maintaining its functionality.
What makes it stand out
